To all whom it may concern.-

Be it known that I, BENJAMIN V. G11.- MORE, a'citizen of the United States, residing at Red House Shoals, in the county of Putnam and State of West Virginia, have invented certain new and useful Improvements in Rail-Brakes, of which the following is a specification. r

This inventionis designed chiefly as an improvement on the device for which Letters atent of the UnitedStates were granted me November 28, 1905, No. 805,644..

The purpose of the invention is to devise a structure which may be quickly and easily applied to a rail and as easily removed therefrom, the frame being constructed in such. a manner as to open and close to clear the need of the rail and being braced when closed by means of the lever, all as will be more fully described hereinafter and pointed out in the appended claims.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eflecting the result reference is' to be had to the following description and accompanying drawings, in Which Figure 1 is a perspective view of a railbrake embodying the invention, showing the same in operative osition. Fig. 2 is a vertical central longitudinal section thereof. Fig. 3 is a transverse section on the line w a; of Fig. 2. Fig. 4 is a view similar to Fig. 2,

modification. Fig. 5 is a perspective view of a further modification, showing the parts separated.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The rail-brake comprises a suitable frame, an operating-lever, and a brake-shoe, the frame being of such construction as to embrace the head of the rail in such a manner as to prevent displacement therefrom.

The frame comprises similar side pieces 1, a connecting-piece2, and inner flanges 3 at pieces 1 and adapted to engage under the head of the rail and sustain upward stress. The inner flanges 3 their upper sides with a covering l -such as leather, wood, or the like-to sustain the wear and engage frictionally with the under side of the head of frame is adapt'edtoppen'orspread to admit of the inner extensions3 clearing) the headof eing placed removedlfrom lthe rail with convenience and despatch. I For this purpose" 6c the rail to permit of-the idevice in position or the frame is constructed toopen lon itudinally, and one or both side pieces are a a ted to move laterall as shown most clear y in Figs. 3 and 5. IT) the preferred construction one of the side pieces is connected to the transverse tie 2 in amannen, to admit of the lower edge swinging outward" and the upper edge inward. he hinge or pivotal joint is indicated at 5, thereby ad mitting of the lower portion of the movable side iece abutting against the proximal longitu inal edge of the tie 2., so as to limitthe' relative inward movement of the flanges 3. and prevent their coming in contact with the web of the rail or the fish-plates at the joints thereof. The movable side piece may be pivoted or hinged to the tie 2 in any manner, and, as shown, lugs 6 and 7 are formed with said parts and are apertured to receive the pintles connecting the pins. 1

The middle portion ofthetransverse connecting or tie piece 2 is formed with an opening to receive a plate 8, which constitutes the brake-shoe and which may be ofany material best adapted for the purpose. The plate or brake-shoe 8 is prevented fromdownward displacement by suitable means,-whioh, as shown most clearly in Fig. 2,. mayconsist of a spring 9 and, as shown in Figs. 4 and 5, of projection and slot. In the construction shown in Fig. 2 a spring 9'is secured to each end of the brake-shoe and projects therefrom to overlap the part of the tie 2 bordering upon the 0 ening in which'the brake; shoe is fitted. n the construction shown in Fig. 4 a teat or projection 10 is formed or provided upon the inner-edge of thepart 2 bordering upon the opening in which the brake-shoe is fitted and enters a slot 11;, formed in the edge of the brake-shoe, the slot projection 10 being so disposed as to admit of the brake-shoe having a limited vertical play without dropping through the opening of the tie 2 when the device s removed from the rail. In the construction shown in Fig.5 the slot 12, formed in eachend of the brake-shoe 8, is closed at its upper and lower ends and receives the inner end of the pin 13 the rail at each side of thewebthereof. The

hinged or pivotally employed for pivotally connecting the side pieces or membersof the'frame. This con? struction prevents both vertical and downward displacement-of the brake-shoe when the device is disengaged from the rail.

The operatin lever 14 is formed with a cam-head 15v of awidth corresponding a proximately to the transverse extent of t e tie 2 or the distance between the side pieces 1, so as to fit snugly between said side ieces and prevent inward displacement t ereof about the transverseconnecting or tie piece 2, thereby holding the inner flanges or lower bra e members; in position for cooper- 'at ion with the head of the rail; The operat- 'ing-lever. is preferably connected to theframe at a .point midway of its ends and is removably fitted thereto, so as to admit of separating or spreadin the lower portions of the side pieces 1 to enab e the parts 3 to clear the head of the rail, which is'necessary when it may be required to remove the device from the rail or place itin position thereon. Journals 16 pr0 ect from opposite sides of the camformed the side pieces 1, the inner ends of said slots havinilan upper depression 18 to form a seat in w 'GhJthe journals 16 enter to prevent displacement of the cam-lever when the same is under tension or moved to a position to cause the brake members to grip the head of the rail. The side pieces 1 are widened or *formed with extensions 19, in

, which the slots 17 and depressions or seats 18 are formed and which 'obtain a bearing 'a ainst o posite sides of the cam-head 15 to a mit of 51s latter bracing the side pieces 1 to hold them in operative position, so as to sustain and resist the strain when the brake is in art of t e operating-lever or may be pro ectactive 0 eration. The journals 15 may be a mg end portlons of'a in passed transversely through an opening ormed in the head 15. The operatin lever 14 may-be detachably connected the frame inany manner and constructed in any way so long as it serves when in osition to prevent inward move I ment of t e side pieces I and when removed to admit of the side. pieces separating or -brake members 3 to clear the head of the rail.

It will thus be understood that the o cratinglever serves both-as a brace as well asconve'nient means for applying the brake or causing the members 3 and 8 to grip the head of the rail.

In the construction shown in Fig. 5 the transverse connectingepiece or tie 2 is of sectional formation, each section or'ilpart being formed with a side piece 1 and theg-inner edges bein formed with companion knuckles 20, whic are pierced to receive the pintle or ivot-pin 13. This construction admits of Both members orside pieces of the frame a like movement.
